Nice picture of the sewer hose storage,... I use a medium size tub ( 30x18x18, or close) hose folds into it very nice, after I get home from traveling, wash out the tub, hose, parts etc,,, stores in storage compartment below bedroom,,,sparky

Here is another way to store the 3" sewer hoses. The box is an inexpensive plastic tool box from Home Depot 19"X10"X10". I'm able to carry three hose of various length and quality (lower quality = greater length) plus various paraphernalia. The plastic tool box catches any excess water and fits perfectly in the slide out storage bin. When I get home I just add bleach and water, let everything soak for a couple of hours, rinse, dry and repack for the next trip.
